Subject: parse-opt: add PARSE_OPT_KEEP_ARGV0 parser option.
X-Git-Tag: v1.6.0-rc0~66^2~7
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=a32a4eaa36527ab1c9a999357f9edd5e04591a4a;p=git.git

parse-opt: add PARSE_OPT_KEEP_ARGV0 parser option.

This way, argv[0] isn't clobbered when parse-options filters argv[].
